=======================================
Part I: replication files for the main text
=======================================



1. Do files

-------------------------------------------------------------------------------------
1. 1 "Tables 1 and 2_summary Statistics.do"

Used to replicate Tables 1 and 2. 
------------------------------------------------------------------------------------


------------------------------------------------------------------------------------
1. 2 "Tables 3 and 4.do"

Replicates the benchmark results in Tables 3 and 4 in the main text.
-------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------
1. 3 "Table 5.do"

Replicates Table 5, which constructs alternative proxy for firm-level efficiency gap.
----------------------------------------------------------------------------------------------------------------------------------

1.4 "Tables 6 and 7.do" 

Replicates the results in Table 6 and 7, which compares the differential impact of TPU reductions on exporters and non-exporters.
------------------------------------------------------------------------------------------------------------------------------------

1.5 "Tables 8 and 9.do"

Replicates the results in Table 8 and 9.

------------------------------------------------------------------------------------------------------------------------------------


1.5 "Tables 10.do"

Replicates the heterogenous responses in Table 10

------------------------------------------------------------------------------------------------------------------------------------

1.6 "Tables 11 and 12.do"

Replicates Tables 11 and 12.
------------------------------------------------------------------------------------------------------------------------------------


1.7 "Tables 13 and 14.do"

Replicates Tables 13 and 14: input responses, TPU and labor/capital misallocation.
------------------------------------------------------------------------------------------------------------------------------------

1.8 “Table 15.do”

Replicate the robustness checks in Table 15. Note that for columns (4) and (8) in Table 15, the results will exhibit trivial differences with those presented in the main text due to random assignment. 

---------------------------------------------------------------------------------------------------------------------------------------

1.9 "Tables 16 and 17.do "

Replicates Tables 16 and 17 in the main text.


====================================================================================
2.Data files

----------------------------------------------------------------------------------------------------------------------------------------------
2. 1 "labor-basic-tpu-reg-1.dta"

The main data file used for generating the empirical results, containing key variables (e.g., TPU, 
firm-level efficiency gaps, TFP, etc). 
----------------------------------------------------------------------------------------------------------------------------------------------

2.2 "table2custom_us2000-2007ex.dta"

This data file contains export information for the matched sample ("labor-basic-tpu-reg-1.dta").

-------------------------------------------------------------------------------------------------------------------------------------------------

2.3 "table2custom2000-2007ex.dta"

This data file contains export information for exporters from the Custom dataset. 
-------------------------------------------------------------------------------------------------------------------------------------------------
2.4 "yong_export_us_new.dta"

This data contains firm-level export information to the U.S., i.e., a firm whether exports to the U.S. market.

-------------------------------------------------------------------------------------------------------------------------------------------------

2.5 "adjustcost2.dta"

This data file contains various proxies for firm-level firing costs: 1. minimum wages, 2. city-level average wages; 3. the number of employer-employee disputes.

-------------------------------------------------------------------------------------------------------------------------------------------------

2.6 "city1998-2007.dta"

This data file contains the number of firms at the city-industry-year level. 

-------------------------------------------------------------------------------------------------------------------------------------------------

2.7 "fdi1998-2007.dta"

This data file contains a variable measuring FDI at the city-industry-year level.
-------------------------------------------------------------------------------------------------------------------------------------------------

2.8 "data_input2.dta"

This data file is used in Columns 4-7 of Tables 13 and 14. This dataset contains variables measuring firm-level import information, e.g., import status, import intensity and number of imported products
-------------------------------------------------------------------------------------------------------------------------------------------------

2.9 "indrategrowth.dta"

This data file contains a variable measuring industry-level import growth.
--------------------------------------------------------------------------------------------------------------------------------------------------

3.0   "labor-basic-tpu-reg-us-provcic2000.dta" and "labor-basic-tpu-reg-us-provcic98-00.dta"

The first dataset contains a variable measuring the share of exports to the US at the province-industry-year-level, along with other firm-level variables.
The second dataset contains a variable measuring the share of exports to the US during the 1998-2000 period at the province-industry level. 
These two datasets are used to create Table 16,
